A character — good or evil, male or female, young or old — who never gives up. Ever. No matter what.
There is no stopping the Determinator. They do not understand tact. They do not Know When to Fold 'Em, and it's a waste of time to tell them the odds. No one can reason with them. They'll do whatever they have to without question. No price is too great to pay for success, up to and including their own life. Do not expect them to realize they might be better off letting it go, even if they can barely stand. If you're ever kidnapped or lost with no hope of rescue, they'll be the one who will find you. Their adversaries will shout, in exasperated rage, "Why Won't You Die?!". For them, there is no line between "perseverance" and "insanity."
The nobility of their goal is not necessarily proportionate to their persistence. This is just as often an obsessive rival with a grudge as it is a hero on a chivalrous quest, and where their willpower ultimately leads them will depend both on their role and on where the work stands on the Sliding Scale of Idealism vs. Cynicism. Heroes — especially Badass Normals with a Screw Destiny attitude — will defeat villains by virtue of being too stubborn to stay down. Anti Heroes will Jump Off The Slippery Slope, forsake The Powers of Love and Friendship, become like that which they fight, and walk the thin line between victory and tragedy. Villains will refuse to admit defeat, resist seemingly fatal punishment, hunt their prey tirelessly and relentlessly, and let the heroes know that We Will Meet Again. And mailmen will always get your mail to you. More inhuman beings such as monsters or an Eldritch Abomination may just also be The Juggernaut, and this will present a serious problem for the heroes who may have to find some MacGuffin just to survive as it endlessly plows through everything and refuses to take a break.
Compare and contrast with Implacable Man (or woman)— while a Determinator pursues their goal through sheer willpower, the Implacable Man is driven by artificial, unnatural, or magical means, and often suffers no apparent damage at all.
Compare Suicidal Overconfidence, a common feature of many Video Game genres where enemies will always, blindly, and relentlessly be at your throat with no regard for how horribly you are massacring them (though this is more due to genre requirements than characterization). Compare Tragic Dream, where becoming a Determinator can only end in tears. Can be identified by their trademark Determined Expression.

- Lucretia from The Adventure Zone is the anti-hero variety of this trope. She worked unrelentingly for a decade to almost single-handedly reverse the damage of the Grand Relics, protect her friends, and keep the Hunger away, although her methods were certainly questionable. This attitude and behavior are explained in the Stolen Century arc as being the result of a year she spent on the run from the Judges while they rest of her crew was imprisoned.
- The long haul trucker Narrator of Alice Isn't Dead is stubbornly persistent in her quest to find her wife Alice, to get an in-person explanation for the mysterious, Conspiracy-laden circumstances around Alice's disappearance, even though this search draws her into unwitting, unwilling encounters with the paranormal.
Narrator: Ill keep driving this truck. Ill keep wandering this country. Im going to find you. I will.
- Starlee, host of Mystery Show, sticks with her cases until the very end. One of them even needs a Time Passes Montage in the middle, and her client teases her about it:
David: Maybe this is just your update where it's like, "I have no idea who Jake Gyllenhaal is, or how to measure human height. Just wanted to let you know I'm still plugging away!"
- Power Star gives us Luigi, depicted here as a valiant warrior who spends the majority of the series in pursuit of his hypnotized brother Mario and stopping him in his rampage. Even when the enemy far outnumbers him in power during the finale, Luigi still doesn't surrender and puts up one last duel with Devil Mario. Saying that he's a far cry from the cowardly video game character is a giant understatement, to put it lightly.
